CURTAIN HANGER.

Specification of Letters Patent.

Patented Mar. 14, 1922.

Application filed J'une 28, 1921. Serial No. 481,000.

resident of New Rochelle, county of Vestchester, State of New York, have invented certain new and useful Improvements 1n I Curtain Hangers, of which the following is a specification. r

This invention relates to curtain fixtures and has particular reference to brackets or supports adapted to be used in connection with curtain rolls employing the conventional form of spring mechanism .for winding the curtain thereupon.

An important object of the invention is to provide in a device of the above mentioned character a means whereby the winding pintle of the spring mechanism maybe positively locked against rotation while-the our t ain roll is being actuated against the spring mechanism, and of such a nature as to permit the pintle to be readily unlocked in order that the spring mechanism employed may be adjusted to a desired tension without necessitating the removal of the curtain roll from its supports.

Another object is to provide a device of the character mentioned which is simple in construction, inexpensive to manufacture and reliable in operation.

Other objects of my invention will become apparent from the following description taken in connection with the accompanying drawings, in Which Figure 1 is a fragmental elevation of a curtain roll, the pintle of which is'supported or retained by the device embodying my invention.

Figure 2 is a sectional view taken on line 22 of Figure 1.

'F'gure 6 is a sectional view taken on line 6-6 of Figure 1; and

Figure 7 is a sectional 77 of Figure 5. V

In the drawings, attention being called to Figures 1 to 3, inclusive, wherein is shown the preferred form of my invention, the numeral 5 indicates a window frame with which view taken on line the conventional type of curtain roll 6 is as sociated, the curtain roll 6 being provided with a curtain 7 adapted to be rolled upon or unrolled from the curtain roller 6. The end of the curtain roll 6, not shown in the drawings, is adapted to be rotatably mounted upon or connected to the window frame 5 by any of the well known types of brackets employed 'for supporting curtain rolls, but the opposite end, which is provided with the ordinary pintle 8 having the usual connection with the spring mechanism, not shown, for operating the curtain roll, is supported by the bracket or fixture embodying my invention and indicated as a whole by the numeral 9. The fixture 9 comprises a base plate 10 adapted to be attached to the window frame 5 by means of nails or screws as shown at 11, the base plate 10 being provided with a boss or flange 12 having a central bore 13 and cut away as shown inFigures l and 2 to provide an entrance slot 14. It will be noted that the central bore 13 of the boss 12 is so formed as to provide a canrfaced terred'to. Within the'boss 12 there is disposed a rotatable pintle-receiving element 16, one end ofwhich is provided with a flange 17 adapted to be seated upon the bearing surface18 at the joiuture of the base 10 with the boss 12. The rotatable pintlereceiving element 16 is provided therein with a slot 19 adapted to register with the opening 14- in order that the pintle 8 may be inserted into the pintle-receiving element 16 or readily removed therefrom.

In the event that it becomes necessary to adjust the spring mechanism, not shown, of the roller 6 to a desired tension, it is unnecessary to remove the pintle 8 from the pintlereceiving element 16, inasmuch as the adjustment may be accomplished by unrolling the curtain 7 from the curtain roll 6 against the tension of the spring mechanism, not 'shown,'after which the curtain roll 6 is rotated in an opposite direction by hand to roll the curtain 7 upon the same. By reason of the fact that the pintle 8 normally resting upon the cam face 14L and in contact with the abutment 15, it is apparent that the same is held against rotation when the curtain 7 is being unrolled from the curtain roll 6 against the tension of the spring mechanism thereof not shown; but it is also apparent that by reason of the inclination of the cam surface 14;, the pintle 8 will be lifted or elevated into the pintle-receiving groove 19 when the curtain roll 6 is rotated in an opposite direction, the pintle 8 being held against rotative movement with respect to the roller 6 by the usual form of pawl and ratchet mechanism not shown. After having rolled the curtain 7 upon the curtain roll 6 by hand as above described, the pintle 8 will drop by gravity to th position shown in Figure 2, when the curtain '7 is again unrolled from the curtain roll 6 against the tension of the spring mechanism, in which position the pintle is locked against rotation when the curtain 7 is being unrolled from the curtain roll 6 against the tension of the spring mechanism. By repeating the above described operations it is obvious that the tension of the spring mechanism not shown of the curtain roll 6 may be adjusted to any desired strength without necessitating the removal of the pintle 8 from the pintle-receiving element 16.

Attention being directed now to Figures ito 7, inclusive, wherein is shown amodified form of my device, it will be noted that the device indicated as a whole by the numeral 20 comprises a base 21 adapted to be secured to the window frame 5 by means of screws or nails 11 in the manner hereinbefore mentioned in connection with the form of my device indicated by the numeral 9, and that the base 21 is struck up to form a yoke 22, provided with a boss 23 which is cut away as shown in Figure 5 to form an entrance slot 23 and provided with a central bore 24 adapted to receive a rotatable pintle-receiving element 25 having a slot 26 formed therein adapted to register with the slot 28' in order to permit the insertion of the pintle 8. The pintle-receiving element 25 is provided with a sprocket 27 which as shown .in Figure 4 is positioned intermediate the yoke 22 and the window frame 5. Over the sprocket 27 there is passed a chain 28 by means of which the. sprocket 27 together with the pintlereceiving element 25 is rotated in the direction indicated by the arrow shown in Figures 5 and 6, in order that the spring mechanism, not shown, of the curtain roll 6 may be adjusted to any desired tension, as will hereinafter more clearly appear. In order to prevent the intle-receiving element 25 from rotating with the curtain roll 6 when the curtain 7 is being un-rolled from the curtain roll 6 against the tension of the spring, not shown, I provide aplunger 29 which is disposed within a passage 30 formed within the pintle-receiving element 25, the plunger 29 being adapted to reciprocate within the passage 30 and engage an abutment 31 adjacent the cam face 32. It is obvious that by the construction which I employ the pintlereceiving element 25 may be rotated in the direction indicated by the arrow in Figures :5 and 6, but that its rotation is prevented in the opposite direction when the curtain is being unrolled from the curtain roll 6 against the tension of the spring mechanism not shown.

To adjust the tension of the spring mechanism, not shown, of the curtain roll 6 to a desired degree, by the modified form of my de vice the curtain roll 6 is prevented from rotating by holding the curtain 7, whereupon the pint-le-receiving member is rotated in the direction indicated by the arrows shown in Figures 5 and 6 through the instrumentality of the sprocket 27 and its associated sprocket chain 28, until the desired tension is reached.
